High Carbon Stainless Harbor Freight Machete, Cut, Grind, HT in Heat Treating Knives, Blades etc Posted March 10, 2019 Harbor Freight's Machete is made of "High Carbon Stainless Steel," I'd guess it's 7Cr17MoV, but I'm really not sure, since it's cheap and chinese. This is all guessing, and Step 5 would be started within 1 hour of step 2. But here's my off-the-wall idea: 1. Cut and Grind smaller knives from Harbor Freight machete made of "High Carbon Stainless Steel." Not sure how to anneal this. 2. Heat until non-magnetic. 3. Air Quench to room temp. (I read 1 post that said it was an air quenched metal, but I'd prefer to oil Quench.) 4. Place between Dry Ice Blocks to cryo treat to -109 F. (I've no idea if this will help) 5. Temper at 335 F for 4 hours 6. Place between Dry Ice Blocks to cryo treat to -109 F. (I've no idea if this will help) Any critiques, suggestions or ideas at all are appreciated!
